/**
 * Describes font size hints used by the JGoodies Windows look&amp;feel; future
 * implementations of the Plastic l&amp;f may use the same hints.
 * <p>
 * 
 * These hints are only applied if the dialog font is <em>Tahoma</em>, which is
 * the default font on the majority of Windows desktops. The hints apply a size
 * delta to increase or decrease the given system font size.
 * <p>
 * 
 * NOTE: This is work in progress and will probably change in the next release,
 * to better reflect the font choice in the J2SE 1.4.".
